Answer:
lungs
Explanation:
lungs
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
The lungs exchange gases

Explanation:
The purpose of ______ is to pass a copy of a cell's gene to cells in the next generation. The purpose of ______ is to pass the parents' genes onto the next generation.
The purpose of reproductive cells is to pass a copy of a cell's genes to cells in the next generation. The purpose of somatic cells is to pass the parents' genes onto the next generation.
Reproductive cells are specialized cells involved in the process of sexual reproduction. In humans and many other organisms, reproductive cells include sperm cells in males and egg cells (or ova) in females. These cells are produced through a unique cell division process called meiosis, which reduces the number of chromosomes in half to create haploid cells.
Somatic cells make up the majority of an organism's body and are involved in various functions, such as growth, repair, and maintaining bodily functions. Unlike reproductive cells, somatic cells are diploid, containing two sets of chromosomes—one inherited from each parent. While somatic cells do not directly pass their genes to the next generation, they play a crucial

Activity: Write in your own words and understanding how do soil formed and identify the factors that helps in the formation of soil.
don use any searching app in answering
Soil is formed by the weathering of rocks which takes place over millions of years. Hence, soil formation is a slow process.
Soil formation takes place in different layers namely topsoil, subsoil, partly weathered rock and parent rock or bedrock.
The topsoil is rich in humus and supports all types of vegetation. Subsoil consists of sand, silt, clay and holds moisture.
Factors Responsible for Soil Formation :The parent rock determines the colour, the texture and mineral composition.Climate controls the rate of weathering, time decides the maturity of soil.Plants and animals contribute to humus formation and the relief of the land determines the accumulation of soil.Answer:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

total saturation of protein transporters for a given solute in the renal tubules would result in __________.
Answer:
absence of that solute from the urine
Explanation:
A protein transporter is involved in the transportation of the ions and the molecules. If a membrane protein transporter gets totally saturated in the renal tubules, then that solute will appear in the urine.
What are transport proteins?Transport proteins are the transporters that move the molecules, ions, and macromolecules in and out of the cell. They carry the molecules and substances across the biological membrane and allow their diffusion.
If a transport protein saturates a solute totally in the renal tubules, then that solute will get secreted in the urine as they are easily soluble in the water and the fluid of the excretion system.
Therefore, the solute will get excreted in the urine.

chromosomes from blood drawn from a five-day-old baby appears to have slight facial deformities and has been diagnosed with an atrial heart defect
Answer:
A congenital heart defect (CHD) is a heart problem that a baby has at birth. It is caused by abnormal formation of the heart during growth in the womb. In most cases, when a baby is born with a congenital heart defect, there is no known reason for it. Some types of congenital heart defects can be linked to an abnormality in the number of a baby’s chromosomes. They may be linked to single gene defects. Or they may be linked to environmental factors. In most cases, there is no clear cause that can be found for the heart defect. They are often thought to be caused by many factors. The factors are usually both genes and the environment. This means that genes from both parents plus unknown environmental factors lead to the problem.

Answer:
Prevention is the most cost-effective and safest method of controlling invasive species. Detecting invasive species early and responding quickly is far more effective than trying to control a vast infestation. Invasive species may be subject to control and management efforts if eradication is not achievable.
